negative indices in array ranges
by Martin Baehr 14 Aug '26

14 Aug '26

hi, instead of having to do: reverse(reverse(foo/"/")[1..]); i'd very much prefer: (foo/"/")[..-2]; are there any reasons that speak against supporting this other than me not being able to offer a patch? greetings, martin.

levels might possibly be from -1 and up, -1 meaning infinite.

managing comport settings in linux
by Henrik Grubbstr�m (Lysator) ＠ Pike (-) developers forum 09 Apr '26

09 Apr '26

Not a good idea; the design philosophy of Pike is that Pike-level code should never be able to cause memory corruption at C-level. With ioctls there's no way to know what data a specific ioctl wants without reading the documentation for that specific ioctl for that specific OS. ioctls and fcntls are a way for device handlers to hook in APIs that aren't standard across all filedescriptors. / Henrik Grubbström (Lysator) Previous text: >2004-08-17 13:32: >Subject: managing comport settings in linux >-------------------------------------------------------------------- >What would be nice, is a way to define ioctl methods in >Pike.

Re: Playing music using pike and SDL.

Were you not able to get any C code to play through SDL either? Does your SDL library have a mixer compiled in it (I think it is optional)?

GC fatal
by Stephen R. van den Berg 22 Apr '10

22 Apr '10

The following error has been occurring in all 7.8 Pike versions for the past 9 months (at least). I have a production machine running Roxen which crashes on an error like this roughly once a day. I'm willing to make custom changes to the production environment in Roxen and/or Pike to track this one down. Things that slow down the production environment for more than a factor of three are not acceptable. Any suggestions on how to tackle this problem? /data/src/gpike/src/gc.c:2519: GC fatal: Marked a thing without refs. **Block: 0xab493890 Type: object Refs: 0 **Got gc marker at 0xbcacbb0: flags=0x00000 refs=0 weak=0 xrefs=0 saved=-1 frame=(nil) **Program id: 66369 **The object is not on the object link list. **The object is destructed but program found from id. ******************* **Looking for references to 0xab493890: **Done looking for references to 0xab493890, found 0 refs.

I just tried converting Roxen 2.4: Stage Memory use Commits --------------------------------------- Import 339 MB ~17000 Raking 359 MB ~17000 Verify 361 MB ~17000 Merging 662 MB 11886 Graphing 803 MB 10897 Generate 803 MB 10897 I believe that the memory use can be reduced by using more custom datatypes (currently there are a lot of mappings generated in the merging and graphing stages). Another way to reduce the memory use is to partition the graphs in the time axis.

port.c does not work in CONFIGURE_TEST mode?

On eureka-git.lysator.liu.se: --------------------- $ make configure [...] checking if union initialization works... yes checking if port.c works in CONFIGURE_TEST mode... no configure: error: port.c does not work in CONFIGURE_TEST mode. This is an internal problem in Pike. configure aborted since further configure tests will be unreliable. gmake: *** [configure] Error 1 --------------------- Is this a known issue?

Re: Testsuite failures (Re: Gz.FIXED and Windows build)

The OS X manpage for ld mentions a "-macosx_version_min" option, are we correctly applying that one? I'm assuming it needs to match the number used for __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ for things to work out as intended.

SO_REUSEADDR after an accept()?
by Stephen R. van den Berg 20 Feb '10

20 Feb '10

Why are we setting SO_REUSEADDR on a filedescriptor/socket that came from an accept()? (in socket.c) IMO that seems useless. For a socket used in a bind(), it makes sense, but not for anything else. Any insights? (Henrik? You touched that piece of code last). -- Sincerely, Stephen R. van den Berg. A sign seen in a jewelry store window: "Ears pierced while you wait"

socketpair_ultra?
by Stephen R. van den Berg 17 Feb '10

17 Feb '10

It appears that Hubbe tested socketpair() and found it to return EAGAIN and EADDRINUSE on occasion on AmigaOS? Even though all the UNIX manpages list it as incapable of returning either EAGAIN or EADDRINUSE? Anyone here who can still recall the circumstances? I can't even begin to imagine why the socketpair() call would fail with an EADDRINUSE. Any clues? -- Sincerely, Stephen R. van den Berg. I'm NaN.

Inf, NaN, DBL_MAX, HUGE_VAL
by Stephen R. van den Berg 16 Feb '10

16 Feb '10

While struggling with Solaris and a native Pike compilation, I stumble across some interesting wildlife regarding the definitions (or lack thereof) of +Inf, -Inf and NaN in Pike. Some points of interest are: - On occasion there seems to be a dependency on HUGE_VAL which is undesirable. - Configure is trying to figure out the way floats are stored (big/little endian, IEEE format or not). - In the IEEE case, we hardwire Inf and NaN through their bytewise representation in a union. - In the non-IEEE case we resort to the usage of infnan or HUGE_VAL. I'm just wondering, instead of this plethora of different avenues (some more convoluted and undesirable than others), is there a compelling reason not to define the following two macros as: #define MAKE_INF(s) (DBL_MAX*DBL_MAX*(s)) #define MAKE_NAN() (0.0/0.0) The upside is that DBL_MAX is defined by ANSI C in <float.h> and is bound to be present on all relevant systems. The only reason I could imagine that defining the above macros could pose a problem is with very old C-compilers on systems that generate a runtime error on either of the above two expressions. Then again, in that case you might be better off running older versions of Pike anyway. -- Sincerely, Stephen R. van den Berg. I'm NaN.

Paranoia fix kills performance
by Stephen R. van den Berg 16 Feb '10

16 Feb '10

In the pgsql driver I depend on the fact that I can peek(0) with zero delay. Setting the minimum to one millisecond is rather desastrous for performance. What paranoia is your patch supposed to aid? The old 7.8 code *did* a poll(0) if explicitly told to do so. Please keep it that way. The proper paranoia fix would be leaving the timeout = 1, even though I consider that paranoia unnecessary. -- Sincerely, Stephen R. van den Berg. I'm never wrong.
